What the Tools Do With What You Type

The calculators, generators and checkers run on your device. The words you paste into the readability checker, the numbers you enter into a calculator and the names a generator gives you are not sent to us or to anyone else.

Some tools remember your progress on your own device using your browser's local storage, for example the ticks in the book launch checklist. That information stays in your browser. You can clear it with the tool's reset button or in your browser settings. The same storage remembers whether you subscribed to the newsletter or closed its box, so the site does not ask again.

What Is Processed When You Visit

Like any website, BookBird is delivered by servers that see technical details of each request: your IP address, the page requested, the time, your browser's user agent and the referring page. These are used to deliver the site, keep it secure and fix errors. They are not used to build a profile of you.

The site is delivered through Cloudflare, a content delivery and security network, which processes these request details on our behalf. Cloudflare may set a strictly necessary cookie when it needs to check that a visitor is not an automated attack. Cloudflare's own privacy policy describes how it handles this data.

What We Do Not Do

BookBird does not use analytics trackers, advertising pixels or social media widgets, does not require an account to use any tool, and does not sell or rent personal information.

The Newsletter

If you subscribe, we store your email address, the date you subscribed and which form you used in a database on our own server, to send you the newsletter. Emails are delivered by Postmark, an email delivery service, which receives your address to send them, keeps a record of delivery and unsubscribes, and reports whether a newsletter issue was opened. Links in our emails are not tracked. Your address is not sold or shared with anyone else. Every email has an unsubscribe link; to have your address deleted from our server and from Postmark, write to [email protected].

Your Account

An account is optional. If you create one, we store your email address, when you signed in, and what you choose to save (such as niche reports) in a database on our own server. We sign you in by emailing you a one-time link through Postmark; there is no password. While you are signed in, your browser keeps one strictly necessary cookie that holds your session for up to 30 days; it is not used for anything else. You can delete your account and everything saved in it at any time from the account settings, which also takes you off the newsletter.

When You Buy the Interior Library

Payment is taken by Link, Stripe’s checkout; we never see or store your card details. Stripe tells us the email address you paid with, the amount and an order number, and we keep those in the same database as accounts so that the files appear in your account and so we can handle a refund. Stripe’s own privacy policy covers what it processes for the payment. If you delete your account, the order record is kept only as long as tax and accounting rules require.

When You Email Us

If you write to [email protected], we receive your email address and whatever you include in your message. We use it to reply and keep the conversation for as long as it is useful, and we do not add you to any mailing list.

Your Rights

You can ask what information we hold about you, ask us to correct or delete it, or object to its use. Write to [email protected] and we will answer.

Links to Other Websites

Guides and software pages link to other websites, such as Amazon KDP Help or a product's own site. Those sites have their own privacy policies, which apply once you leave BookBird.

Changes

If the way the site handles information changes, this page will be updated. Last updated: October 6, 2026.
